What is Email ?

Electronic mail, or email for short, is an online message delivery system. It delivers private messages to individuals and groups. These messages are delivered to the recipient’s email inbox, usually within seconds. You can attach files to email messages and even put images within the message body.


Email addresses and mail servers

To participate, you need an email address. You can get this for free from your Internet service provider or from one of the many free web-based email services such as Gmail, Yahoo! Mail, and Outlook.com. Your email address is unique in all the world, like your postal address or phone number is unique.

An email address might look like this: weourdevelopers@gmail.com.

Types of email accounts

  • Web-based: This type of email account is designed to be used primarily with a web-based interface.

  • POP3: This type of email account is designed to be used with an email client, although the provider may also allow web access too.

  • IMAP: This type of email account, like POP3, is also designed to be use with an email client. It does not download received messages, though; it reads them from the server, like web-based email does.            
  • EAS: This type is similar to IMAP except it is used by Exchange servers. It is a popular type of account for groupware and corporate accounts.


  • Emails are delivered extremely fast when compared to traditional post.
  • Emails can be sent 24 hours a day, 365 days a year.
  • Webmail means emails can be sent and received from any computer, anywhere in the world, that has an internet connection .
  • Cheap – when using broadband , each email sent is effectively free.
